"TILE CUTTER. i

Appiiction tied March 3, 192s. serial Nd. 92,021.

My invention relates to rtile cutters, and` particularly to a tool or" this class Whiclris adapted to be rigidly secured to the tile setters mortar board for convenience, and comprises a simple and eilicient means -lor scoring the glazed surface ot tile units such as those used in bathrooii'is and like places. Other advantages and the details ot the invention will be more fully described hereinafter being clearly illustrated in the accompanying drawing, ot' which n Figure 1 is a side elevation ot iiiy iniproved tile cutter;

Fig. 2 is a plan view; Fig. 3 is a transverse sectional elevation taken along the line 3 3 ot' Fig. 1, and

Figs. 4 and 5 are respectively a plan. and transverse sectional elevation of a modifica tion of one ot the details oit my invention. As illustrated in Figs. 1, 2 and 3 ofthe drawing, my invention comprises a rigid trame consisting of a substantially horizontal bar 1v having at one of its ends a down-- Wardly extending point 2 byineans ot which the frame is adapted to be secured to a tile setters mortar board 3, or to some other relatively substantial structure. In some instances the bar 1 may be provided with feet at each ol its ends, for the purpose ot' permanent attachment to a supporting structure.

Adjustably secured tothe frame 1 is an abutment gage 4 provided with downwardly extending lugs 5, 5 which project on either side ot the main bar ot the frame 1. A clamp bolt 6 is provided and passes through apertures formed iii the lugs 5, 5 at a point immediately underlying the main horizontal bar ot the frame 1. -Upon turning the bolt 6, the lugs 5, 5 are drawn into Contact with the frame 1, thereby rigidly securing the gage 4 to said frame.V .The gage 4 also colmprises a. transversely extending bar 7 which forms a. rigid abutment for a tile, X, during the process of scorino'. 1

The bar 7 is provided with an adjustable limit stop 8 having lugs 9, 9 adapted to embrace the bar 7 on its upper and lower surfaces, and being provided With a clamp screw 1() which passes through the upper lug 9 and is .threaded into a correspondingly tapped aperture in the lower lug 9, by means of which the limit stop 8 may be rigidly secured in an adjusted position upon the bar 7. The bar 7 is provided with measurement graduations illustrated at 11, Fig. 2, by

which the position of the limit stop on the transverse bar may be gaged.

cutting tool 12 which is rotatablymountcd in the forked end 13 ot' a horizontally extending bar 14.` The cutter bar 14 extends in a plane substantially parallel to the hori- Zontal element ot' thes frame 1, and issupported upon the lramel adjacent the end opposite the rotary cutter by means ofa roller bearing, coniprisinU a flanged roller 15.

The end oi' the' cutter bar 14, opposite the scoring tool 12, is pivotally attached at 16 to a lever 17, by means of which the scoring tool is traversed across the tile X. The lever 17 is providedat one end with ahandlc and its opposite end pivotally secured at 18 to a link 19, the opposite end of which is pivoted at 20 to the traine 1.

Upon reference to Fig. 2, it will be apparent that the vlever 17l in the present instance, is formed from a continuous piece ot strap metal projectingdownwardly at each side of the cutter bar' 14 and the frame 1; and the link 19 is duplicated ateach side of the ramel in the manner illustrated, a filling Washer 21 being, provided at the pivot 18 for the purpose of acquiring stability at said pivot.

In order to ellect the proper scoring or cutting "ofthe glazed face of a tile, lit is necessary to` apply pressure `to the rotary tool 12, and for this purpose the frame 1 is provided with a vertical extension 25 which coniprises a U-shaped strap extendingbelow the frame `1 and upwards on each side thereof, as illustrated in Fig. 3 being secured to the ,trame by rmeans of rivets- 26, in the present instance. j

Interinediate'tlie upper ends of the extension 25,1 provide a threaded block 27, secured to the strap members of the projection 25 by means ot rivetsj28,-and having a threaded aperture adapted to receive an adjusting' screw. 29, which is provided at its upper end With a knurled head 30 by means of which the screw 2,9 may-be turned vvithin the block 27.

A shoe 31 vis provided adjacent the upper surface olf the cutter bar 14, and has ears 32 extending at each side of the projection 25, by which the sho-e 31 is maintained Within the slot formed in said projection and is permitted vertical movement therein.

iii

lVithin the shoe 31, I provide a compressible element comprisinga block of rubber 33 in the present instance, and upon the upper surface of the pad 33 I provide a plate 3st having downwardly extending tianges 35 which engage the rubber block at each end thereof and secure the plate 34 in position thereon. It will be understood that a spring may be used in place ol the rubber pad 33 for the purpose ot' applying pressure to the cutter bar 14. The screw 29 is adapted to engage the plate 34, as shown in Figs. 1 and 3, for the purpose of controlling the amount ot pressure applied to the cutter bar lll.

In operation, where it is desired to cut tile for various reasons and purposes, the tile setter may adjust the gage limit stop 8 upon the bar 7 to the reading thereon, corresponding to the amount he desires to remove from the individual tile, whereupon the gage limit stop 8 is secured in.position by turning the screw 10.

rl`he rotary scoring or cutting tool 12 normally occupies the position illustrated in broken lines in Fig. 1, and the tile setter places the tile to be cut between the horizontal bar otl the frame 1 and the cutter bar 14, against the abutment bar 7 and the gage limit stop 8, the tile resting upon the upper surface of the frame 1, the rear end of the cutter bar 14 being movably supported upon the roller 15 as clearly illustrated in said ligure.

By turning the screw 29,tl1e operatormay minutely control the amount of pressure applied to the tool 12 through the medium of the compressible element 33. Upon moving the handle 17 in the direction ot the arrow, Fig. 1, the tool 12'is passed over the glazed surface of the tile` as clearly illustrated in the drawings and thereby scores or cuts the said glazed surface ina manner as illustrated at Y in Fig. 2. j

After passing the tool 12 completely across the tile X, the said tool rests upon the upper surface oi the abutment gage 4, whereatter the tile setter may remove the scored tile and upon tapping the tile on its reverse surface the said tile will be broken along the scored line Y, the adjacent broken edges of the tile pieces presenting a comparatively smooth surface substantially perpendicular to the glazed face of the tile and requiring very little or none of the customary stone dressingusually required in order to permit thetile to be set in place.

In Figs. 4. and 5. I have illustrated an abutment gage which may bev adjusted around a denite center in a horizontal plane for the purpose of cutting the tile on any angle desired, and to accomplish this purpose the frame 1 is composed of parallel bars 1 which provide a slot 35 therebetween, adapted to receive a pivot bolt 36 integral with the har 7. Said bolt 36 extends downward from the upper surface ot the bar 1" through a lock plate 37 and is provided at its lower end with a winged nut 38, by means of which the gage bar 7 may be rigidly secured in its adjusted position upon the upper surface of the hars l,

Various modifications may be made to the details of my invention without departing `l'rom the essential features thereof, and only such limitations should be placed thereon as are prescribed in the appended claims o' as may be imposed by the prior art of record. The drawing should in no way be construed at limiting the invention, being an illustration of the preferred 'torni only.
